Abstract

A support system supports the two ends of a passenger-transportation device in a built structure. The support system 6 has a swiveling support-point at a first end with a vertical swivel-axis. The second end contains a floating support-point for absorbing horizontal movements perpendicular to the swivel-axis. The floating support-point has at least one rolling element by means of which a sliding friction caused by the occurrence of horizontal movements in the floating support-point can be transformed into combined sliding-and-rolling friction or rolling friction.

First claim

The invention claimed is:

1. A support system for supporting two ends of a passenger-transportation device in a built structure comprising:
a swiveling support at a first end of the passenger-transportation device with a swivel-axis arranged vertically with respect to its installation position; and
a floating support at a second end of the passenger-transportation device for absorbing horizontal movements that occur perpendicular to the swivel-axis,
wherein the floating support has at least one sliding hearing and at least one rolling element arranged parallel to two side-edges of the at least one sliding bearing for transforming a sliding friction which occurs in the floating support through horizontally occurring movements into a combined sliding-and-rolling friction or rolling friction;
the two side-edges of the at least one sliding bearing extending parallel to a longitudinal extent of the escalator or moving walk.

2. The support system according to claim 1 , wherein the at least one sliding bearing has an upper sliding element and a lower sliding element, each having a sliding surface for mutual sliding engagement.

3. The support system according to claim 2 , wherein a run-up ramp is located on a side-edge of the upper sliding element that faces a rolling element, which run-up ramp provides for a running-up of the upper sliding element onto the rolling element whereby, after a lateral, horizontal movement of the second end, the upper sliding element is at least partly raised from the lower sliding element.

4. The support system according to claim 2 , wherein the floating support has a support-carrier for anchoring on the built structure.

5. The support system according to claim 4 , wherein the upper sliding element is connected with the second end of the passenger-transportation device and the lower sliding element is connected with the support-carrier.

6. The support system according to claim 3 , wherein the at least one rolling element is arranged at the side of the run-up ramp and is connected with the support carrier by a mechanically releasable adhesive, a temperature-stable lubricating grease, an installation grease, or an adhesive grease.

7. The support system according to claim 4 , wherein the support carrier has at least one limit stop for limiting a rolling distance of the at least one rolling element.

8. The support system according to claim 4 , wherein the lower sliding element has a damping element.

9. A passenger-transportation device comprising an escalator or a moving walk with a support system according to claim 1 .
